50K MASHUP SLAM

About the event

The 50K MASHUP is an exclusive ultrarunning series that celebrates the often overlooked yet challenging distance of 50 kilometers. Spanning five races across diverse landscapes throughout the Midwest, this series offers runners the chance to earn a coveted buckle by completing all events in a single calendar year. The journey kicks off with the Frozen Gnome 50K in January and culminates at either the G.O.A.T.z or Miner 49er 50K Trail Race in November.
Each race presents unique challenges, from icy trails to rugged terrain, ensuring that participants experience a wide range of conditions. The series includes notable events like Clinton Lake 50K, Ice Age 50K, and the grueling Dark 2 Dawn endurance challenge spread across six months. Early registrants for the MASHUP gain access to special pricing codes, offering guaranteed entry into select races before they open to the public.
The top three finishers in the series will be awarded based on their cumulative times at each event. All accolades and buckles are presented during the final race of the year, creating a festive atmosphere for those who have pushed through every challenge. This series is not just about running; it's an opportunity to connect with like-minded athletes and explore some of the Midwest’s most scenic trails.
Registration for this elite group closes on January 7th, so don’t miss your chance to join one of ultrarunning’s most respected challenges.
For more information and registration details, visit the official 50K MASHUP website.
